I am using Excel 2000 and have a problem with a sumif formula returning an
invalid solution.

A1:Z9 = range
G1 through G9 =0
A10 = text
B10 = text
C10 = null
d10 = null
e10 = number
f10 = text
g10 = SUMIF(range,"text",G1:G9)

The result of formula in g10 > 0

If I delete column F then the formula result becomes 0 and is valid. If I
delete row 3, the formula result becoems 0 and is valid. Anybody out there
seen something like this before? Any solution?

Thanks
Brian
